Bug Description
Add a tool, tentatively titled smc_eid, to display and set EIDs. Should indicate SEIDs as such.
Notes:
* EIDs are uppercase only - we should silently convert to all uppercase
* Check latest SLD for valid special characters.
* Make sure only authorized users are allowed to modify EIDs - reading is OK for everybody, but writing requires authorization.
* SEIDs can be disabled, but (obviously) not set.
* EID config must be available on module load.
* zOS sets the UEIDs globally, i.e. not separate SMC-D and SMC-R.
Business Case: Required for users that need to strictly separate/prevent certain OS images from utilizing ISM devices for communication (Security). Furthermore, z/OS disables SEID per default, and will likely have users utilize fine-grained EIDs. Hence we need to be able to support UEIDs for compatibility.
This feature is for the kernel part.
